![]() The canopy in the forest is browning and it is expected that trees will drop needles and leaves that can provide some litter cover at the soil surface. In forested communities, the heat from moderate severity fire will result in water repellant conditions at the mineral soil surface. Recovery time in the low category will vary based on ecological community but is expected to recovery in the short-term.Ī moderate category of soil burn severity indicates consumption of litter and fine fuels at the soil surface. Residence time at the soil surface was short, leaving root systems and structure undamaged. The low category of soil burn severity indicate that there was only partial consumption of fine fuels and litter coverage remains relatively intact on the soil surface. The Phase 2 SBS map also shows the acreage for each of the landowners for the 403,473 acres in the Phase 2 assessment to be: 140,206 acres for the Plumas National Forest 125,199 acres for the Lassen National Forest 79,364 acres of private/forestry industry lands 33,585 acres for the National Park Service 23,366 acres of private/unknown lands 911 acres for the State of California-Department of Fish and Game and 839 acres for the DOI Bureau of Land Management. For Phase 2, approximately 39% of the 403,473 acres are either unburned/very low and/or low soil burn severity, while 57% sustained a moderate soil burn severity and only about 3% identified as high soil burn severity. The map and the data display SBS categories of unburned/very low, low, moderate, and high. The BAER specialists recently completed their data gathering and analysis of the Dixie burned area to produce a Phase 1 soil burn severity (SBS) map on August 25-analyzing 365,678 acres, and a Phase 2 SBS map on September 15-analyzing 404,473 acres. ĭue to the large size and continual active burning of the Dixie Fire, the USFS BAER team divided the burned area into three phases for their assessment and analysis. For information about the DOI BAER assessment, please go to the LAVO Dixie Fire webpage found at. The DOI BAER team is currently conducting field reconnaissance of fire impacted recreation facilities, infrastructure, cultural resources, watershed and hydrology, fish and wildlife habitat, rare plants, and invasive species within the LAVO. This DOI BAER team is evaluating post-fire values-at-risk and will recommend stabilization and rehabilitation treatments specific to the LAVO. In addition to the Forest Service (USFS) BAER team that began last month evaluating post-fire effects of the Dixie fire on National Forest System (NFS) lands, a US Department of Interior (DOI) BAER team is focused specifically on the portion of the Dixie fire that burned in Lassen Volcanic National Park (LAVO) and was assembled by the National Park Service (NPS) on September 9, 2021. Post-fire conditions of loss of vegetation and the changes in the soils may increase the flow of water and could cause potential debris and sediment flow impacts. Their focus is on the direct damage caused by the fire itself, rather than from suppression, and the after-effects. ![]() These multi-disciplinary and sometimes multi-agency teams assess wildfire-impacted burned areas almost immediately after the fire threat passes. All Rights Reserved.Burned Area Emergency Response (BAER) teams are sent to federal lands following significant wildfires to identify imminent post-fire threats and give recommendations on how to reduce the potential impacts on human life and safety, property infrastructure, and critical natural and cultural resources.
